Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vacuum cleaner paper bag.

[Prior Art] FIG. 3 is a schematic diagram showing the state of a paper bag in a dust collection chamber of a vacuum cleaner. In the figure, 1 is a paper bag, 2 is a dust collection chamber for storing the paper bag 1, 3 is an air supply fan, and 4 is a suction hose.

Next, this effect will be explained. The vacuum cleaner drives an air supply fan 3, sucks in air and dust from the floor through a suction hose 4, and collects the dust into a paper bag 1 installed in a dust collection chamber 2.

[Problems to be Solved by the Invention] In the above case, as shown in FIG. Opposing surface A
Because of this, the dust passes through the paper bag 1,
The dust accumulates at the bottom B of the dust collection chamber 2, causing a reduction in its collection performance.

The present invention was made to solve this problem, and an object of the present invention is to obtain a paper bag for a vacuum cleaner whose dust collection performance does not deteriorate on the surface directly collided with the suction airflow.

[Means for Solving the Problems] The vacuum cleaner paper bag according to the present invention is characterized in that the openings on the surface directly hit by the suction airflow are closed.

[Effect] By closing the eyes on the surface directly hit by the suction airflow,
The airflow that hits this surface slows down, changes direction, and blows out from the other surface. This improves dust collection performance.

[Embodiment] FIG. 1 is a cross-sectional view showing a main part of an embodiment of the present invention, and numerals 2 to 4 are completely the same as the conventional device. In the figure, a paper bag 1 includes a fine outer layer paper 1a and a coarse inner layer paper 1a with a space therebetween.
It has a double structure of b. Furthermore, the surface of the inner layer paper 1b directly contacted by the suction airflow is provided with a double wrap C larger than the suction port.

Next, this effect will be explained. The surface directly in contact with the suction airflow is double layered with wrap C, which reduces the blow-through of the airflow, and the suction airflow is caused by the inner layer paper 1b.
The pressure is adjusted in the space between the outer layer paper 1b and the finer outer layer paper 1b, and the outer layer paper 1a is blown through. For this reason, dust is collected by the dual filters, one coarse and one fine, and does not escape to the outside.

Next, FIG. 2 is a sectional view showing the main parts of another embodiment, and numerals 1 to 4 indicate the same or equivalent devices as the above-mentioned conventional device. In the figure, thick printing D is applied to the surface of the paper bag 1 that is in contact with the intake air flow, and the vertical and horizontal dimensions L of the area covered with the printing D are relative to the diameter l of the inlet from the suction hose 4. , the relationship l≦L is maintained. By doing this, the inhaled dust airflow will not blow through even if it hits the opposite surface of the suction port. Furthermore, if the printing ink is composed of an antibacterial or deodorizing agent, sanitary and deodorizing effects can be achieved.

According to this embodiment, the eyes of the paper bag on the surface that is hit by the suction airflow are closed, preventing dust from blowing through, and at the same time,
It can improve the dust odor prevention effect.

[Effects of the Invention] As described above, according to the present invention, the dust collection performance is improved by thickening the surface of the dust collection paper bag that is in contact with the suction airflow or by blocking the eyes to make it difficult for the airflow to blow through. I was able to do it.

In addition, since the inside is made of a double bag and made of a material that is rougher than the outside, relatively large dust particles can be captured on the inside, and relatively small dust can be captured on the outside, allowing appropriate capture depending on the level of dust.

Furthermore, since we created a space between the inside and outside,
Since the air at a low speed passes uniformly over the entire surface of the outer bag, there is less dust passing through the outer bag, and there is less clogging of the outer bag.

[Brief explanation of the drawing]

FIG. 1 is a schematic diagram of one embodiment of the present invention, FIG. 2 is a schematic diagram of another embodiment, FIG. 3 is a schematic diagram showing the overall configuration of a conventional example, and FIG. 4 is a state diagram thereof. In the figure, 1 is a paper bag, 2 is a dust collection chamber, 3 is an air supply fan, and 4 is a suction hose. In each figure, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Claims] 1. In a paper vacuum cleaner bag that sucks dust together with air from the suction port, the bag consists of an inner bag and an outer bag spaced apart from the inner bag, and the inner bag is connected to the outer bag. A paper bag for a vacuum cleaner, which is made of a material with a coarser mesh than the bag, and has a double structure in which the part facing the suction port covers an area that is the same as or larger than the size of the suction port.
